CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Korean patent application No.10-2022-0084827, filed on Jul. 11, 2022, the entire disclosure of whichis incorporated herein by reference.

TECHNICAL FIELD

The disclosure relates to a fixing plaster for fixing a drain tube, andmore particularly, to a plaster for fixing a drainage tube, which blocksboth lifting and longitudinal movement of the drainage tube, andfurthermore, does not cause pressure on the skin, thereby causing nopain and maintaining a good fixation state.

BACKGROUND ART

The drainage tube is a discharging tube for guiding liquid generated ina body cavity to the outside of a body, and is inserted into the bodythrough a separate passage after an incision portion of the body issutured during surgery. A drainage bag is connected to an end of adrainage tube. The drainage bag accommodates the liquid that escapesthrough the drainage tube.

Because a drainage tube is a transparent tube made of synthetic resinand has flexibility, the drainage tube can be easily bent according to apatient's movement or posture change. When the drainage tube is bent,liquid cannot pass therethrough, and, when time passes withoutdiscovering the fact that the drainage tube is bent, bacteria mayproliferate in the liquid stagnant in the body, and the pressure in thebody may rise, causing the surgical site to burst.

In installation of the drainage tube, it is important to fix thedrainage tube so that it does not come off. There are several methods offixing a drainage tube, one of them is a method of fixing a drainagetube by knotting a surgical suture to the drainage tube. However, in themethod of fixing a drainage tube by using a suture, the drainage tubecannot be firmly fixed. For this reason, other fixing means instead ofsutures have been proposed.

As a background technology of the invention related thereto, a drainagetube fixing member has been disclosed in Korean Utility ModelRegistration No. 20-0489503.

The disclosed invention relates to a drainage tube fixing member forfixing a drainage tube inserted into a human body to remove drainage andinflammatory exudate generated during wound healing after surgery, thedrainage tube fixing member including an attachment fixing part attachedto a patient's surgical site and a drainage tube fixing part coupled tothe attachment fixing part to fasten and fix a drainage tube exposed tothe outside of the human body. The drainage tube fixing part includes aguide support portion coupled to the attachment fixing part toselectively support a vertical or horizontal state of the drainage tube,and a fastening portion fastened to the guide support portion tomaintain a vertical or horizontal state and configured to fasten andsupport the drainage tube exposed to the outside of the human body. Theguide support portion includes a lower support coupled to the attachmentfixing part and having a cutout portion wider than the outer diameter ofthe drainage tub at the center of the lower support, and a fasteningportion support extending upwards from each side of the cutout portionto fasten and support the fastening portion and having a guide holeformed from a lower portion of the extension to an upper portion thereofto have a ‘ 7’ shape.

Conventional general drainage tube fixing devices have insufficientdesigns for pressing. For example, a component part included in adrainage tube, such as a 3-way valve, may press the skin and cause pain,but conventional general drainage tube fixing devices do not have astructure for preventing such pressure.

DETAILED DESCRIPTION

An embodiment of the disclosure will now be described in more detailwith reference to the accompanying drawings.

A plaster for fixing a drainage tube according to an embodiment to bedescribed later maintains a stable fixation state by blocking bothlifting and longitudinal movement of the drainage tube inserted into apatient's body.

For reference, the drainage tube includes a flexible tube having one endinserted into the patient's body and the other end to which a drainagebag is connected, a 3-way valve installed in the middle of the flexibletube, and a connector for connecting the 3-way valve to the flexibletube. Two of the three ports of the 3-way valve are connected to theflexible tube through the connector.

FIG. 1 is an exploded perspective view of a plaster 10 for fixing adrainage tube according to an embodiment of the disclosure, and FIG. 2is a plan view schematically showing a drainage tube mounted on theplaster 10 shown in FIG. 1 .

As shown in the drawings, the plaster 10 according to the presentembodiment has a pair of support pads 11, a support band 13, and twoholders 20.

Each of the support pads 11 is a sheet-type member that is adhesivelyfixed to the patient's skin and has a certain thickness, and has anadhesive foam 11 a on its bottom surface. The adhesive foam 11 amaintains the adhesion state of the support pad 11. The support pad 11has flexibility and thus may closely adhere to the patient's skin. Theshape or size of the support pad 11 may vary.

An adhesive cloth 14 a is fixed onto an upper surface of the support pad11. The adhesive cloth 14 a is a member attached to an adhesive cloth 14b on a bottom surface of the support band 13, which is to be describedlater. Velcro fabric may be used as the adhesive cloths 14 a and 14 b.However, snap buttons may be applied instead of the adhesive cloths 14 aand 14 b.

The support band 13 is a member having both ends detachably fixed to theupper surface of the support pad 11 and configured to cover the skin.The material of the support band 13 is the same as that of the supportpad 11.

The support band 13 has a support 13 a and restraining protrusions 13 c.

The support 13 a takes the shape of a rectangular plate having a certainthickness, and, as shown in FIG. 2 , supports a 3-way valve 201 andconnectors 202 and separates them from the skin. A reason for supportingthe 3-way valve 201 and the connectors 202 is to prevent the 3-way valve201 and the connectors 202 from pressing on the skin and causing pain.When there is no support 13 a, the 3-way valve 201 may cause injury orpain by pressing the skin.

The adhesive cloths 14 b are fixed onto respective lower surfaces ofboth ends of the support 13 a. As described above, the adhesive cloths14 b are members attached to the adhesive cloths 14 a provided on thesupport pads 11. Adhesive cloths 15 a are provided on respective uppersurfaces of both ends of the support 13 a. The adhesive cloths 15 acorrespond to adhesive cloths 15 b fixed to the holders 20,respectively.

The restraining protrusions 13 c are formed at both ends of the support13 a, come into contact with the connectors 202, and prevent movement ofthe connectors 202. In other words, the connectors 202 on both sides areprevented from departing in a direction indicated by arrow a. Movementof a drainage tube 200 in a longitudinal direction is prevented by therestraining protrusions 13 c. The longitudinal direction refers to anextension direction of a flexible tube 203.

Accommodation grooves 13 e are provided in the restraining protrusions13 c, respectively. The accommodation grooves 13 e are grooves ontowhich the flexible tube 203 is fit. As the flexible tube 203 is fit ontothe accommodation grooves 13 e, the flexible tube 203 does not shake inleft and right directions.

The holders 20 are members detachably coupled to the upper surface ofthe support band 13. For example, each of the holders 20 has a structurein which a rectangular sheet is folded about a folding line 21 e, andaccommodates each of the connectors 202 therebetween.

The holder 20 includes a folding sheet 21 and adhesive cloths 23 a and23 b. The folding sheet 21 is a flexible synthetic resin member that isfolded or unfolded about the folding line 21 e. The folding sheet 21adheres to the connector 202 in a folded state and constrains theconnector therein.

The adhesive cloths 23 a and 23 b are folding holding portion fixed to afore end of an inner surface of the folding sheet 21, and maintains astate in which the folding sheet 21 is folded. When the folding sheet 21is folded with the connector 202 placed thereon and the adhesive cloths23 a and 23 b are attached to each other, fixing of the connector 202 tothe holder is completed. As the connector 202 is fixed to the holder 20,there is no lifting of the drainage tube 200. In other words, thedrainage tube 200 is not separated from the support band 13.

An adhesive cloth 15 b is fixed to the lower surface of the foldingsheet 21. The adhesive cloth 15 b is detachably attached to the adhesivecloth 15 a of the support band 13.

FIG. 3 is an exploded perspective view of a plaster 10 for fixing adrainage tube, which is a modification of the plaster 10 for fixing adrainage tube according to an embodiment of the disclosure. FIG. 4 is aside view of the plaster 10 of FIG. 3 .

The same reference numerals as the described-above reference numeralsindicate the same members with the same functions.

Referring to the drawings, it may be seen that a protective housing 30is detachably mounted on the support band 13. The protective housing 30serves to provide a protective space above the support band 13. A 3-wayvalve is accommodated in the protective space 30 a. The reason foraccommodating the 3-way valve in the protective space 30 a is, forexample, to prevent a switching lever 201 c (see FIG. 2 ) of the 3-wayvalve from being caught by an external object and turning, while thepatient is moving. When the switching lever 201 c turns abnormally, adrainage passage may be blocked, and bacteria may enter through the3-way valve.

The protective housing 30 includes an elastic plate 33, an outer shell31, and adhesive cloths 35 b. The elastic plate 33 is formed by bendinga rectangular plate, and has a substantially C shape in a state where noexternal force is applied. Of course, the elastic plate 33 may befurther bent or unfolded by applying an external force.

The outer shell 31, which is a synthetic resin member surrounding theelastic plate 33, may be manufactured by injection molding. In otherwords, the outer shell 31 may be manufactured by positioning the elasticplate 33 in a mold and then injecting a resin. The outer shell 31 isprovided with an access hole 31 a. The access hole 31 a, which is athrough hole, exposes a syringe connection port 201 a (see FIG. 2 ) ofthe 3-way valve to the outside. An injection needle may be inserted intothe syringe connection port 201 a through the access hole 31.

The adhesive cloths 35 b are members fixed to respective inner surfacesof both ends of the outer shell 31, respectively, and are attached toadhesive cloths 35 a located on the lower surface of the support band13. The protective housing 30 may be fixed to the support band 13through the adhesive cloths 35 a and 35 b.

FIGS. 5 through 7 are views showing modifications of the support band 13in a plaster for fixing a drainage tube, according to an embodiment ofthe disclosure.

A stretchable portion 13 p composed of a plurality of slits 13 g isapplied to the supporting band 13 shown in FIG. 5 . Each of the slits 13g extends in a width direction of the support 13 a, and the plurality ofslits 13 g are parallel to each other. The slit 13 g serves to increasethe length of the support band 13 when a tensile force is applied to thesupport band 13. For example, when a distance between the support pads11 increases according to a movement of the patient, the length of thesupport band 13 is increased.

The plaster 10 to which the stretchable portion 13 p is applied issuitable for installation at a joint portion. This is because, whenevera patient bends a joint, the distance between the support pads 11increases and thus tension is applied to the support band 13.

Three accommodation grooves 13 e are provided in each restrainingprotrusion 13 c. Of course, a desired accommodation groove among thethree accommodation grooves 13 e is used.

In FIG. 6 , elastic pleats 13 k are applied as the stretchable portion13 p. The elastic pleats 13 k have a wavy pattern and increase in lengthwhen a tensile force is applied to the support band 13.

A valve groove 13 m is formed in the support 13 a of the supporting band13 shown in FIG. 7 . The valve groove 13 m accommodates the 3-way valve201, and more stably restrains the 3-way valve 201. In addition, aprotrusion height of the 3-way valve 201 may be reduced by applying thevalve groove 13 m. In other words, the height of the 3-way valve 201relative to the upper surface of the support 13 a is lowered. Due tothis lowering of the height of the 3-way valve 201, the probability thatthe 3-way valve 201 is caught by an external object when a patient movesis reduced.

FIGS. 8 through 10 are perspective views of holders 20 applicable to theplaster 20 for fixing a drainage tube according to an embodiment of thedisclosure.

The holder 20 shown in FIG. 8 has a friction cushion 25 on one side. Thefriction cushion 25 is a member made of soft silicon, and has aplurality of locking grooves 25 a. The friction cushion 25 serves tomore stably fix the connector 202. For example, even when the flexibletube 203 is pulled from the outside, the connector 202 does not slip outof the holder 20 due to friction with the friction cushion 25. Thelocking grooves 25 a double the fixing force of the connector 202. Whena protrusion is formed on a connector depending on the type ofconnector, the locking grooves 25 aa provide a more powerful fixingforce by accommodating the protrusion.

The other side of the folding sheet 21 is provided with a confirmationhole 23 d. The confirmation hole 23 d opens a connection portion betweenthe connector 202 and the flexible tube 203 upward. Through theconfirmation hole 23 d, it may be visually confirmed whether theconnector 202 and the flexible tube 203 are normally connected to eachother or whether they are about to be disconnected from each other.

In the holder 20 of FIG. 9 , one side portion of the folding sheet 21 isdivided into three branches. The three branches, which are separationtabs 21 a, more precisely fix the connector 202. For example, when thereare many irregularities on an outer circumferential surface of theconnector 202, the separation tabs 21 a are coupled to concave portionsof the irregularities other than convex portions thereof.

An elastic sheet 27 is applied to the holder 20 shown in FIG. 10 . Theelastic sheet 27 is a rubber or silicon sheet that is elasticallydeformed by an external force, and stretches when the folding sheet 21is pulled in a direction indicated by arrow k. Due to this applicationof the elastic sheet 27 that is elastically deformable, the connector202 having a large diameter may be fixed without any problems.

While the disclosure has been particularly shown and described withreference to exemplary embodiments thereof, it will be understood bythose of ordinary skill in the art that various changes in form anddetails may be made therein without departing from the spirit and scopeof the disclosure as defined by the following claims.
